I recently upgraded a Joomla 1.5 site to 2.5. I needed to expire a article, but the publishing options weren’t there. I am still learning 2.5, and needed to figure it out. Here is what I saw.
There was no place to set the published and unpublished dates. Back out the to the list of articles and click on “options.”
Under Editing Layout make sure “Show Publishing Options” is set to “Yes”. Mine was set to yes, but wasn’t show. Click “save and close”.
Now, the publishing options should be there.
